VALVE-LIFTER.

' Specification of Letters Patent.

Application filed August 13, 1920; Serial no. 403,202.

Valve-Lifter, of which the following is a full, clear, and comprehensive specification and exposition, the same being such as will enable others to make and use the same with exactitude.

The object of my present invention. broadly speaking, is to provide a valve lifting tool which is positive in action, simple in character, easily operated and adjusted, and which can be manufactured and sold at a comparatively low price. I V

More specifically stated my object is to provide a tool for releasing and replacing the puppet valves in explosion engines, the same having means whereby the tool may be adjusted to operate with varioussizes and types of motors, and, having means whereby the valve may be rotated by the tool when the tool is in operation.

Other minor objects and particular advantages of the invention will suggest themselves in the course of the following specification, and that which is new will be cor related in the appended claims.

The preferred meansfor carrying out the objects of my invention in a practical and economical manner is shown in the accompanying drawings, in which-Fignre 1 is a side elevation of my tool as it would appear in actual practice releasing a valve shown in connection therewith, certain portions of the motor being shown in vertical section in order to'show the interior thereof. Fig. 2

is a side elevation of my tool alone, showing.

the jaws open or spaced apart.

Fig. 3 is a central vertical section, on an enlarged scale, showing certain portions of mytool, also showing parts of a valve and the valve mechanism. Fig. 4B shows one of thepronged bits alone. 5 showsa blade bit alone, and Fig. 6 shows a plan view of the spring engaging jaw of my tool.

Similar indices denote like parts throughout the several views.

In order that the construction, the operation, and the advantages of my invention may be more fully understood and appreciated I will now take up a detailed description thereof, in which I will set forth the several features as fully and as comprehensively as I may.

' for in the'bottom Referring now to the drawings in detail Letter A denotes a portion ofan explosion motor, the same havlng an explosion chamber B, and an intake or exhaust chamber C. The chambers B and G being divided from each other by the partition D which is formed integral with the motor. LetterE notes the bottom of chamber C.

Formed'through the partition D is the valve aperture G,'whose upper portion is formed flaring thereby providing the valveseat for the valve H which fits therein to close theiaperture Gr.

Integral and concentric with the valve H denotes the too of chamber B, and F deis the valve stem 1, which extends'clown' through the center of the aperture G, and.

through a guide or hearing aperture'thereextends. V

Formed laterally through'the lower portion of the stem 1 is an aperture in which,

onthe pin J and prevent the removal of said pm, but when the washer is moved upward F, below which thestem then the pin maybe easily removed endwise.

Formed through the top E 'is-a comparatively large threaded aperture L,.the same ordinarily being closedby afplug screwed therein. Letter M denotes the, valve spring which surrounds the stem L, and it is normally in contact with the under side of they bottom F, and with surface of the washer,

K, to hold the valve in its seat.

My invention proper-includes a pair of crossed handles 1 and 2, which are pivotally connected by the bolt 3. .From near the bolt 3 said handles are turned at substantially..

right-angles to their respective 'main portions thereby forming the respective shanks sand 5 which other. 7

Integral with but, projecting forward at right-angles from the shank 4 is the arm 6, and extending downward and forward from the latter is the finger 7 which terminates in the bearing member'8 which has a vertical aperture therethrough.

Extending forward from the shank 5 the material is given a quarter turn or twist to project oppositely to each form the flat disk-like and forked plate 9, whose forward portion has a notch 10 therein, in which may enter the stem 1, thereby forming the two thin points 11 and 12 on each side of the notch 10 which may be inserted between the coils of the spring M, or between said spring and the washer K.

Rotatably mounted in the bearing 8 isthe shaft 13 which has a head 14 on its upper end, and below the bearing 8 the shaft 13 is threaded to receive thereon the collar 15 which is rigidly secured thereto.

)Tumerals 16, 1'7, 18 and 19 denote the bits, each having a stem to fit in the lower portion of the collar 15 where it may be detachably secured by means of a set-screw 20. Said bits differ from each other either in the length of their stems or in the working ends of the bits for instance, the bits 16, 17 and 18 have different length stems but they each have points 21 adapted to fit in cavities therefor in the top of the ralve H, as in Figs. 1 and 3. Or if the valve is provided with a channel across its top then a bit with a blade 22 is provided as that shown in Fig. 5.

Numeral 23 denotes a lever or handle secured in the head 1d to afford means for turning the shaft and the bit secured therewith.

Operation: Desiring to use the tool the proper bit is first secured in the collar 15, depending on the size of the motor, after which the tool is opened, as in 2, and the bit is then inserted through the aperture L, bringing the bit into connection with the valve as shown in Figs. 1 and 3.

The handles 1 and 2 should now be opened to bring the plate 9 under the'lower end of the spring M, or between two coils of said spring, the plate 9 being then pressed between the spring and the washer K. Now

by grasping the handles 1 and 2the operator may force said handles toward each o her, which manifestly will contract the springM and raise it above the washer K thereby enabling the operator to easily lift the washer and then remove the pin J. By means of the lever. 23 the operator will be enabled to turn the valve and the stem whereby the pin J will be turned to the most accessible position for the operator to remove it. then by turning the lever 23 they may be revolved and thereby loosened.

As soon as the pin J is removed then the washer K will drop off the stem thereby per- Also if the valve or the stem be stuck mitting the spring M also to be removed. After the above the tool should. be removed, after which it is evident that the valve may be removed b lifting it upward through,

, thereby accomplishing the I desire that it be understood that various changes may be made in the various details of construction without departing from the spirit of the invention and without sacrificing any of the advantagesthereof which are new and useful.

Having now fully shown and described my invention, what I claim anddesire to V secure by Letters Patent of the United States, is

1. A valve lifting tool oomprisilig a pair of crossed handles pivoted together, a notched plate carried by one of the handles and adapted to be inserted astride a valvestem for engagement with the valve-spring,

an arm and a finger carried by the otherone of said handles, a bearingcarried by said fingenrotatable means mounted in said bearing, means for revolving said rotatable means. and a removable bit connected to said rotatable means and adapted to engage a valve for holding the valve in its seat and nabling the valve to be turned, all substantially as shown and described. i

2. A valve lifting tool comprising a pair of crossed members forming handles at one I end, a spring engaging member located on one of the working ends and a removable bit mounted opposite to the letter on the other working end, and means whereby said bit may be rotated independently of the operation of said crossed members, all substantially as shown and described A valve manipulating tool comprising in combination means for releasing the pressure of the valve spring from the valve,-

and means carried by the tool for rotating the valve and the valve stem, substantially as set forth. a V

In testimony whereof I have hereunto subscribed my name to this specification in the presence of two subscribing witnesses.
